Tag Archives: Typeahead

When working with non-editable AngularUI Typeaheads (i.e. ones that have the typeahead-editable attribute set to false), a logical thing to do would be to erase the typeahead input field’s view value if the user doesn’t select a valid typeahead option. However, there’s no built-in option to do just that, so here’s a workaround.

The main idea here is to use the ng-blur attribute to set a function that will clear the typeahead field if no valid option was selected. To do that first we need to access by name the form controller object containing the typeahead. If the typeahead is not contained in a form element, what we can do is declare one of its parent elements as a form controller using ng-form, and give names to both of them:

Now we can access the the typeahead’s form properties from the AngularJS controller, and reset its $viewValue property if no valid option was selected by the user. We wrap this into an AngularJS $timeout because there’s a delay between clicking on an option and the corresponding model updating. Don’t forget to inject the $timeout service into your controller!
